Patrick Chung was signed by the Patriots on April 4, 2014.
April 4, 2014 update On April 4, 2014 ESPNBoston.Com's Mike Reiss reported that "Looking closer at the contract signed by Patriots safety Patrick Chung:
Term:1 year
Base salary: $740,000
Signing bonus: $60,000
Workout bonus: $60,000
Roster bonus: $240,000 ($15,000 per game based on being on 46-man roster)
Salary-cap charge:$1.04 million
QUICK-HIT THOUGHTS: This deal comes in a little bit higher than anticipated, as Chung can collect $120,000 between workout and signing bonuses even if he doesn't make the club. It reflects, from this view, some form of competition in signing him. The projection was that his deal would have been closer to a minimum-salary benefit, which would have cut the salary-cap charge almost in half. Still, it's far from a bank breaker for a player who faces competition to earn a roster spot."

January 10, 2015 update On January 9 ESPNBoston.Com's Field Yates reported that "Chung received a $2.4 million signing bonus. He will earn base salaries of $1 million in 2015, $1.4 million in 2016 and $1.8 million in 2017. The deal includes roster bonuses of up to $200,000 in each season (paid per week based on being on the 46-man game-day roster), with an additional $900,000 in incentives in 2016 and 2017. On the incentives, Chung will earn $200,000 for playing at least 60 percent of the defensive snaps, $500,000 for playing at least 70 percent of the defensive snaps, or $900,000 for playing at least 80 percent of the defensive snaps each season."
My Notes: Field Yates also reported that the deal contained $3.4 million in guarantees. Seems safe to presume that Chung's 2015 $1 million salary is fully guaranteed. Chung played in 76.7% of the defensive snaps in 2014.
